To all whom it may concern:

Be it known that I, Lnwrs T. Wrnoox, a citizen of the United States, anda resident of Peekskilhin the county of VVestchester,

State of New York, have invented certain Ovens, of which the followingis a specifica supplied from a point below theovemas when it is placedovergas or oil burners- Such ovens are usually provided wlth an openbottom and means for-causing the dis tribution of the heat so that thebaking'or roasting of food therein will be effectively anduniformlydone. -They are also provided with doors havingtransparentportions through which the condition of the interior of theoven and the food in process of cooking may be observed Without openingthe said door. It is to ovens of this class that the improvementsrelate. Their objects will appear from the followingspecification andthe accompanying drawings referred to herein.

In the said drawings, Figure 1 is a front elevation of an oven embodyingthe improvements with a portion of the front broken away. Fig. 2 is ahorizontal sectlon of the same on the line 22 ofFig. 1, looking in thedirection indicated by the arrows in that figure. Fig. 3 is an enlargedvertical section on the line 3-3 of 2, looking in the directionindicated by the arrows in that figure.

The frame of the oven consists of four.

walls 1, 2, 3 and 4, a cover 5, and a bottom 6, the front Wall 1 is cutout to provide openings for the door and Windows and the bottom has alarge central opening, through which heat passes from the burners to theinterior, the edges of the metal around this opening being turned up toform a flange as shown at 7 (Fig. 1');

A substantially elliptical ring 8 is horizontally supported inside theoven on bosses 9, upon which rest the offset portions 10 0f the ring.Two sets of these bosses are provided on the interior surfaces of theinner walls 11, 12 and 13 of "the oven, one above the other, so that thering 8 may be raised and lowered and supported thereby in lts upper orlower position. The top of'the BAKING-OVEN.

ing in the bottom of the oven so as to in tercept the heat rising-fromthe burners and cause it to pass up along the inner walls of the {ovon.-"The corners of the oven are angular and"the corners of the tray 14 arerounded, sothat a substantially triangularl space is left at the fourcorners and the dis--' tance between the corners and the tray is greaterthan the distance between-the tray and the walls at intermediate points;By this provision a larger opening for the up wardpassageof heated airis provided at the corners the points most distant from the burners, anda more uniform" distribution of the heat thus caused; The curvatureofthe corners ofthe tray, however, is on a shorter radius than that ofthe pans or dishes usually employed to hold food to be cooked, sothatthe edges of the said pans may come incontact with the walls withoutprojecting materially beyond the tray. Such a pan is indicatedbythe'dotted lines in Fig. 2, the inner circle of dotted linesrepresenting the bottom ofthe'pan and the outer-circle representing theupper outer edge. "This pan is also shown at 17in Fig.

:1, in which it is shown to be flared from the bottom up and providedwith an annular rim or flange 18." The primary objects ofthis provisionare tooprevent theedges of the pan from interfering materiallywith theupwardspassageof heat and alsoto in-- sure that liquid overflowingfromthe pan will fall onth'e tray 14. Such liquid does not usually fallsheer from the rim of the pan but turns inwardly and drips therefrominside the outer edge of the rim, and in most cases from thebottom ofthe pan, and as the bottom of the pan will always be Within the outeredges of the tray, the tray thus catches such drippings and protects theburners beneath it.

radiationfof heatqfrom the burners tothe medial part of the oven is thusinterrupted to a sufiicient extent to prevent overheating and burning ofthe cooking food at this part of the oven.

The tray 1 1 is formed by stamping up a sheet of metal, then applyingthe false bottom and then turning over the edges of the metal to securethe edges of the false bottom. It is thus formed without the useofsolder or other similar means for uniting the two parts.

The door 20 is hinged at 21 to the front wall 1 and is provided with abracket 21, the lower end of which slides on the bail 22 fixed to thefront wall, and theupper end of which is secured on the ring 23 of thedoor, so that the door will be supported thereby when opened and turnedoutward substantially at right angles to the front wall.

The upper edge of the door is provided with a latch consisting of asuitable knob on the outer side of the oven, and the tongues 25 and 26secured to and turning with the knob. These tongues extend in oppositedirections from the shank 27 of the knob and are. provided with bosses28 and 29 respectively, which bear against the bead 30 and boss 31 ofthe front wall and oven respectively when the knobis turned to securethe door in its closed position, thereby insuring a tight closure of thedoor.

What I claim is:

1. A device of the character described, comprising an oven shell orcasing composed of walls, a top, and a bottom, one wall being providedwith a door opening and the bottom having an opening for the admissionof heat, said ovenadapted to be placed upon suitable burners and saidbottom opening extending over one or more burners, a door for openingand closing the door opening, a tray supported horizontally in the saidoven below the upper part of the door opening, said tray covering andextending beyond the bottom opening and being spaced from the walls ofsaid oven a greater distance at the corners of the even than at pointsintermediate said corners, the said spaces at the corners being less attheir greatest width than one-fourth of the length of the shortest ovenwall.

2. A device of the character described, comprising an oven shell orcasing composed of walls, a top, and a bottom, one wall being providedwith a door opening and the bottom having an opening for the admissionof heat, said oven adapted to be placed upon suitable burners and saidbottom opening extending over one or more burners, a door for openingand closing the door opening, a tray supported horizontally in the saidoven below the upper part of the door opening, said tray covering andextending beyond the bottom opening and being spaced from the walls ofsaid oven a greater distance at the corners of the oven than at pointsintermediate said corners, the said spaces at the corners being less attheir greatest width than one-fourth of the length of the shortest ovenwall, and the corners of said tray being curved on a radius greater thanthe greatest width of said space.

3. A device of the character described, comprising anoven shell orcasing composed of walls, a top, and a bottom, one wall being providedwith a door opening and the bottom having an opening for the admissionof heat, said oven adapted to be placed upon suitable burners and saidbottom opening extending over one or more burners, a door for openingand closing the door opening, a tray supported horizontally in the saidoven below the upper part of the door opening, said tray covering andextending beyond the bottom opening and being spaced from the walls ofsaid oven a greater distance at the corners of the oven than at pointsintermediate said corners, the said spaces at the corners being less attheir greatest width thanone-fourth of the length of the shortest ovenwall, and spacing members supporting said tray from said oven walls atthe back and ends of the oven.

Witness my hand this 20th day of June, 1916, at the city of New York, inthe county and State of New York.
